MS-120XFZY Specifications
• Frequent scanner resets
• Scanner occasionally loses power (due to host initiated shutdown)
• Occasional host lockups.
Because multi-interface Miniscan Plus products are often exposed to these environments
due to the nature of scanner placement, they have been safeguarded as much as possible
to prevent physical damage. Despite design precautions, testing has shown that some USB
hosts cannot tolerate these environments. In this case, try placing a self-powered USB hub
close to the host, between the scanner and host, as a buffer to the host against the harsh
environment. This may not be a valid solution in all cases.
